IMPROVEMENT IN HAND-STAMPS.

The chednle referred to in thes'e Letters Patent and making partofthe same.

To all whom it may concern: l Y

Be it known that I, THOMAS S. HUDSON, of East' Cambridge, in the county of Middlesex, and State of Massachusetts, have invented certain Improvements in Hand-Stamps, of which the following is afull, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figure l is a front elevationof a hand-stampwith my improvements applied thereto.

Figure 2 is a central vertical section oli the line x v of fig. 1.

Figures 3, 4, and `5, details and modifications to be referred to.

My invent-ion consists in indicating upon the frame of a hand-stamp, or upon -a plate or other device attached thereto, a series of letters, figures, or characters, which shall serve as a guidefor bringing into their proper position those required for stamping-the impression, whether the guiding-letters," figures, or characters be stationary or movable, and whether they .be placed upon the head of lthe frame or on its top or side, and whether their position be in a horizontal or vertical plane, or in a plane inclined thereto and, in' connection with the above,

My invention also `eonsistsmin a movable or stationary calendar, bearing the naines or portions of the names of the days of the week.

To enable others skilled iu the art to understand and use my invention, I will proceed to describe the manner in which I have carried it out. l

All the operating-portions of the stamp are constructed in any known way suitable for staLmps of the kind.

1n addition` to these known devices, I provide the following features constituting my invention.

I is a circular met-al plate, bearing the figures and letters representing the years, days of mouths, and

other characters usually required in hand-stamps for printing dates, Sto. e

This circular plate revolves freely ou an axis, consisting of a pin, m, screwed into the front of the head of the frame-work.

Fitting over a smooth portion of this pin, and sef` cured immovably thereon by a spline and feather, is a segmental plate, K, bearing letters which serve as a calendar for representing the names of the days of the week.

An index, L, pointed at both ends, n o, is also fitted over the screw-pin, between the calendar-plate K and head of the pin, (see iig. 3,) the index being slipped loosely thereon, `so as to be free to be moved by hand for the following ptupose:

It being desired to stamp the date, March 4, 1869, upon a slip of paper placed on the bed or table b, the

figures 69 are brought in line with the upper end,

n, of the index L, when it will be seen that the lower end, o, of the pointer stands opposite the figures 74. Now withdraw the pin g from its position in one of the holes in the side of the year-wheel O, and hold it away from contact therewith while revolving the said wheel around,ftill the figures 74 are exposed to view at the top of thelopening between the bifurcated portions of the plunger, just below the circular plate I, when the pin g may be allowed to spring back into one of its holes, and prevent the wheel from revolving.

The position of these figures (74) on the type-wheel D is such, that when at this point, the figures 69 will be found on the edge of this wheel, at its lowest point, ready for stamping its impression.

Next, turn 'thecircular plate I around till the'let-A ters Marare brought opposite the upper end, n, of the pointer, when the letters Aug will be found opposite the lower end, 0, of the index or pointer L. Now withdraw and hold back the pin l from its hole in the wheel D, till it is revolved sufliciently to bring to view (opposite the figures 74) the letters Aug on the edge of said wheel, when the pin t is allowed to fall into itsl hole, and thereby prevent its revolution.

WVhen these letters Aug are in the position above referred to, the letters Mar *will be found on the edge, at lowest point of the ywheel D, in their proper position for stamping their impression, and opposite the figures 69.

Next, bring the ligure 4, on the circular plate I, around in line with the upper end, n, of the index or pointer L, and the ligures 17' will be found in line with the lower end, o, of the pointer, when onlwithdrawing the pin h from its hole in the circular plate on the hub ofthe wheel E, and turning this wheel till the-figures A17 are brought up to view in the line with 7 4 and Aug, the pin his allowed to ,be pressed back into its proper hole in the circular plate on the hub of the wheel E, thus preventing the middle wheel E from revolving, and the required ligure, 4, will be found in its proper position for stamping the impression.

The `figures representing the days of the month maybe brought in line with the names ofthe days of the week corresponding thereto on the segmental plate or calendar K, -by simply turning the circular plate'I around until vthe proper figures are brought in. line with the respective days of the week, occurring on those particular days of the month.V

In the foregoing description, I have spoken of the circular plate I, and index or pointer L, revolving on their axis m, while the calendar K, representing the daysof the week, was stationary thereon, but if desired, the circular' plate I may be stationary, and the calendar K and pointer L may revolve on the axis fm, The plate I, with an indicator, L, 1n combination or the circular plate I and calendar K may both move with the printing-wheels of a hand-stamp, substan and the pointer L be stationary. tially as and for the purpose described.

Furthermore, the circular plate may be dispensed Also, a calendar-plate, K, in combination with the with, and its` letters and figures be nade directly on plate I, snbstantially'as and for the purpose set forth. an enlargement of the head of the frame-work, as seen ,Y THOS.

What I claim as my invention, and desire to secure N. W. STEARNS, by Letters Patent, is- Y. W. J. OAMBMDGE.
